This script acts as a front-end for xpilot.  Run it in the background, and it will pop up a window for each server it finds running.  Press the \"?\" button for this info.

This program polls each xpilot server once a minute.  To make it poll immediately, press \"update\".  Press \"play as\" to enter the current game with the alias to the right.  Edit to taste.  (Your alias is initialized from the value of xpilot.name in ~/.Xdefaults.)

Double-click the left button on an alias to see the real user name.  To remove the user name window, click on it with the left button.

Pan the world/author text, player list, or your own alias by holding the middle mouse button down and moving the mouse."
